Kayak quietly introduced its Private Sale exclusive hotel deals, where Kayak, in an apparent travel-metasearch first, collects the booking and credit-card details from the consumer.

The basics look a lot like Jetsetter: Both Kayak and Jetsetter enable consumers, who have registered for these private offerings, to access a handful of what are said to be exclusive hotel deals for a limited period of time. Incidentally, the only thing — for now — that makes these hotel deals private is that you have to register for free to access them.
